What would you do without them? Seriously, if every single battery of every single type were suddenly zapped out of every single thing that it operated, what would any of us do?
With its integrated L.E.D. light, you never have to be troubled about operating in dark locations. This relieves the anxiety of constantly having to carry a flashlight with you.
Use lithium stocks copyright the battery. Li-Ion safety circuits do a lot of great things to keep it in good condition, but they're going to go south if you don't use them. There is no wonder they're stored charged to half-capacity. If you most often use your netbook using AC power while you're at home, make sure that you let it run to the point where windows gives critical battery level warning at least two or three times a week.
Avoid deterioration from heat. Lithium-Ion accumulator cells used in today's notebooks are extremely vulnerable to heat. The notebooks are designed in a way that they drive heat away from the battery, but there are steps you can take yourself. Never close the lids on the bottom side, you can easily do that by putting them on a firm surface instead of your legs. Don't push them all the way in to the wall or against the wall with their exhaust lids as this is equally dangerous. Avoid direct sunlight whenever you can, choose a spot in your room where sun doesn't shine on the computer directly.
People know that communication is very important and there will be times when the batteries of the cellphones are drained and there are no outlets in sight. At least with cheap cell phone batteries the owner can stock up and put these to their cellphones and make those Lithium battery stocks emergency calls.
What are you going to be using the drill for? Let's say that you are planning on building some light furniture and maybe will use the drill on weekends mostly. You probably don't need a super powerful drill with the most expensive battery technology. You could probably get by with a 12 volt drill, no need for hammering action, and you could probably do fine with a NiCad battery as opposed to Lithium Ion. Sure, a Lithium mines Ontario Ion battery would be really nice, and would charge faster, but if you aren't planning on using the drill for continuous hours at a time you could save a few bucks in this department.
Memory effect will reduce the life of a battery. Modern Lithium-ion batteries do not suffer from memory effect, although it does occur in Nickel-Metal Hydride (NiMH) units when charged from levels other than 0% of battery capacity. If the (NiMH) unit was fully charged when initially at say 20% capacity, the resulting available capacity would only be 80% of the factory original. Of course every time you charged the battery, the total available capacity would reduce and eventually your mobile phone would prove to be increasingly useless. Nearly all new electronic devices are now powered by Lithium batteries. You should always condition your (NiMH) battery from new.
And that's about it; not so hard, right? So, although lithium ion batteries might keep us on our toes, utilizing these few simple practices will help you keep your batteries performing at their peak for a whole lot longer. Respect your stuff and in return you'll enjoy really great results.
